Cerebral palsy is one of the most common motor disabilities in early childhood. It is defined as a set of varying, but permanent disorders of movement, position and posture. These disorders result from prenatal, perinatal or postnatal brain damage, malformation of immature brain or from disturbances that occured in the developing fetal or infant brain. Prevalence of cerebral palsy is 2 to 3 per 1000 live births. The clinical picture of cerebral palsy is very complicated. It consists a lot of disorders and difficulties of which the most important are communication, language and speech difficulties. Communication difficulties are present in 42 % of children with cerebral palsy and speech difficulties are present in 36 % of children with cerebral palsy. There are data that suggest that speech and language difficulties are present in approximately 31 – 88 % of children with cerebral palsy. In fact, if speech difficulties are severe, language production will be more disrupted. Language is very important because it allows the exchange of messages between children and their conversation partners. Therefore, this paper will tend to provide an comprehensive overview, description and the critical review on the effectiveness of some approaches that speech language pathologist can use in rehabilitation of communication, language and speech difficulties in children with cerebral palsy. Thus, in this paper are described clinical picture of cerebral palsy and above mentioned communication, language and speech difficulties. Of course, particular emphasis is placed on the approaches. These approaches are: assistive technology, alternative and augmentative communication, interaction training for conversation partners of children with cerebral palsy, PROMPT approach and systems approach. After literature review it is noted that the highest efficiency demonstrate alternative and augmentative communication, PROMPT approach and systems approach. Two remaining approaches are less effective. Those approaches that are not mentioned and described in this paper are approaches that are less represented in the literature. Moreover, for many of them there are no studies which demonstrate the effectiveness of their application in work with this population. Therefore, the need of those studies is big, as well as the need of those studies related with approaches that are mentioned in this paper. Namely because some of them showed certain limitations that should not be ignored.
